SPECIFICATION forming part of Letters Patent No. 257,340, dated May 2, 1882.

Application filed January 16, 1882. (No model.)

To all whom it may concern:

Be it known that I, JiiRcEN KASSCHAU, of the city, county, and State of New York, have invented certain new and useful Improvements in Oil Founts or Reservoirs, of which the following is a specification.

This invention has reference to an improved oil fount or reservoir for student and other lamps.

In the accompanyingdrawings,Figure 1 represents a vertical central section of the fount of a studentslamp. Fig.2 is a detail vertical transverse section on line at m, Fig. 1; and Fig. 3 is a vertical central section of areservoir arranged to supply a number of lamps.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents an oil fount or reservoir for students or other lamps, said fount or reservoir being of any suitable size and shape, and provided at the lower part with one or more oil-discharge pipes, B, the common opening a of which is closed by a vertically-guided and spring-actuated valve, 0, at the bottom of the t'ount or reservoir. The valve 6 is tightly pressed against the seat a of the opening a of the discharge-pipe B by its spring whenever a spindle, D, which is pressed down upon the valve 0 by means of a screw-cap, D, at the top of the fount or reservoir, is-released. This is accomplished by unscrewing the cap D, whereby the pressure upon the valve 0 is removed and the The spindle D is guided by a fixed diametrical guide-piece or bridge, I), at the top part-of the fount, and by a socket, d, or other guiding device at the lower part of the same, the lower end of the spindle being made of fork shape, so as to straddle the discharge-pipe and pass alongside of the I same to the valve 0, as shown clearly in Fig. 2.

The spindle D is provided near the fillingorifice of the fount or reservoir A with a float,

D of cork or other suitable material, by

which the spindle is lifted so as to project to some distance above the upper edge of the top opening whenever the fount or reservoir is filled with oil to the proper height. The float D is stopped by the bridge b when the fount is practically filled. The screw-cap D is then screwed in and hermetically closed by means of an interposed elastic washer, e.

I The fount may be used in connection with a single or double students lamp; or it may be arranged as acentral supply-reservoiron the top floor of a building, it being in this case connected with the lamps in the building by means of oil-supply pipes, which extend down to the lamps and into the founts of the same, as shown in Fig. 3, the central reservoir supplying the oil to the lamps in the same manner as but with considerable less trouble than in the common students lamps.

It the reservoir be made large enough, a large number of lamps can be supplied, which is of great advantage in factories, public and private buildings. The central reservoir has,

however, to be provided with a waste-pipe for discharging the contents, in case of fire, into the sewer. The lamps of each story may also be supplied by a separate pipe, so as to prevent any possibility of an overflow.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 7 The combination of a fount or reservoir, a screw-cap at the top thereof, an eduction-pipe having a valve-opening opposite the screweap, a spring-actuated valve adapted to close'
